Tutorial: How to Install RELATE on Fedora CoreOS Latest

In this tutorial, we will guide you through the steps required to install RELATE on the latest version of Fedora CoreOS. RELATE is an open-source software package that is designed to simplify the task of deploying scientific software packages on high-performance computing clusters. RELATE provides a single uniform interface for the management and orchestration of computing resources.

Prerequisites

To follow this tutorial, you will require the following:

A server running the latest version of Fedora CoreOS
A user account with sudo privileges
Internet connectivity

Step 1: Install Dependencies

Before we can install RELATE, we need to install some dependencies that it relies on. We can do this using the dnf package manager.

Open Terminal on your Fedora CoreOS system.
Log in as a user with sudo privileges.
Run the following command to update the system package list:
```
sudo dnf update
```

Install the following dependencies:

sudo dnf install -y gcc make cmake openmpi openmpi-devel hdf5-openmpi hdf5-openmpi-devel boost-openmpi boost-openmpi-devel python3 python3-devel numpy pandas cython h5py

Step 2: Clone the RELATE Repo

Now we need to get the RELATE package from the official GitHub repository using Git. We will clone the repository to the current directory.

In Terminal, navigate to the directory where you want to clone the repository.

Run the following command to clone the repo:

git clone https://github.com/LLNL/relate.git

After cloning is complete, navigate into the newly cloned directory:
```
cd relate
```

Step 3: Build and Install RELATE

Now that we have the RELATE source code on our system, we can build and install it.

Run the following command to build the RELATE package:
```
make build
```
After the build completes, run the following command to install the package:
```
make install
```

Step 4: Verify the Installation

We can verify that RELATE has been installed correctly by running a simple test. This will ensure that the installation was successful and that the package is working as expected.

In Terminal, navigate to the directory where the RELATE package is installed:
```
cd <INSTALL_DIR>
```
Replace <INSTALL_DIR> with the directory where RELATE was installed. By default, it is installed in /usr/local.
Run the following command to run the test:
```
bin/oarsim --version
```
This should display the version number of OAR, which is the software that RELATE uses for resource management.

Congratulations! You have successfully installed RELATE on your Fedora CoreOS system.

Conclusion

In this tutorial, we walked you through the steps required to install RELATE on the latest version of Fedora CoreOS. By following these steps, you can quickly and easily deploy scientific software packages on high-performance computing clusters using RELATE.
